Ultimately createAndSwallowExceptions here is wrong I imagine. Presumably you
want to actually do something when serializing data fails (although the spec
seems pretty weird in this area... but that's a separate issue).

Something like the code in
https://code.google.com/p/chromium/codesearch#chromium/src/third_party/WebKit...
would probably be what you'd want to end up doing (except with the peculiarity
that the payments spec seems to require swallowing exceptions from parsing and
failing with a different exception instead).

But since you're not actually accessing m_serializedData anywhere yet (and not
validating any of the other arguments either) it might just be enough to not
parse at all?

Done.
